That's what the Mini iOSD is for. You'll also need to get the CAN bus cable adapter that the P2 comes with.
Or you can get one of those Chinese OSDs that install inline with the GPS (search "naza lite osd").

Thanks.. Would that work with the MC on the P2 V+? I have read on different forums that the V+ MC is different from the P2.
Can the V+ accept a hub? Do I really need a hub if I dont have many cambus items?

There are 3 cables from that attach to the gimbal board. 2 of them are bridges to power up the wifi module.
You can redirect the wifi module cable back into the CAM port. This will give you no video but will power up the wifi module with telemetry data. Just connect wifi to phone as per normal. The only problem is how to get that info back into the Fatty sharks.

If you do this, you are half way from connecting a H33d and gopro to a vision+.

Mako79, can you share more info about the function of the three cables, and how to redirect the wifi module cable back into the CAM port? I would like to remove my gimbal/camera but still get telemetry info. I am trying to protect my gimbal while I practice, then put it on when I want to capture videos.
Thanks!
